Abstract (en)

Methods and systems are disclosed for solving a regression problem, for example a data regression problem and/or a differential equation problem, over a problem domain using a hybrid computer system. The hybrid computer system comprises a quantum computer system and a classical computer system. The method comprises receiving or determining, by the classical computer system, a regression problem description and a set of kernel points in the problem domain. The method may further comprise receiving or determining, by the classical computer system, a trial function associated with the regression problem, the trial function being based on a quantum kernel and being parameterized by one or more kernel coefficients. The quantum kernel may be based on an overlap of two wave functions. The method further comprises determining, using the quantum computer system, for each of the kernel points, a kernel value of the quantum kernel and/or a kernel derivative value of a derivative of the quantum kernel. The method further comprises determining, by the classical computer system, a set of optimal kernel coefficients based on the kernel value and/or kernel derivative value and determining, by the classical computer system, a solution function based on the trial function and the set of optimal kernel coefficients.
